== Sample 3

This sample demonstrates the use of transactions, including container-managed transactions on the consumer side.
The listener receives a batch of messages and sends them to another topic, all within one transaction.

Run the application and use curl to send some data:

`$ curl -X POST http://localhost:8080/send/foos/a,b,c,d,e`

Console:

[source, bash]
